The purpose of this study was to determine the effects of 8 weeks of circuit strength training (CST) followed by 8 weeks of jogging and then 8 weeks, of CST or jogging. During the final 8 weeks, the subjects were randomly assigned to either CST or jogging groups. The subjects (n=16, x age = 29 yrs) exercised 3 days/week. The strength training involved 2 circuits of reciprocal exercises using isokinetic devices with 10 to 15 repetitions/set and 30 seconds of rest between sets. The subjects jogged 3 miles/day during the jogging program. After the initial 8 weeks of CST, significant changes were found in treadmill performance time, maximum oxygen uptake (VO2max), maximum pulmonary ventilation (VEmax), body fat, total skinfold fat, fat weight, lean weight, isotonic bench and leg press, and isokinetic slow speed, fast speed, and power endurance measures. The jogging program elicited significantly greater changes in treadmill performance time and VO2max. Further reductions were found in total skinfolds and waist girth during the jogging program. Leg strength was maintained during jogging but upper body strength was reduced significantly. Physiologic levels were maintained during the final 8 weeks and showed no differences between the CST and jogging groups.
本研究的目的是确定8周循环力量训练（CST），接着8周慢跑，然后再进行8周CST或慢跑的效果。在最后8周，受试者被随机分配到CST组或慢跑组。受试者（n = 16，平均年龄 = 29岁）每周锻炼3天。力量训练包括使用等动设备进行2组对抗性练习，每组重复10至15次，组间休息30秒。在慢跑阶段，受试者每天慢跑3英里。在最初8周的CST之后，发现跑步机运动时间、最大摄氧量（VO2max）、最大肺通气量（VEmax）、体脂、总皮褶厚度、脂肪重量、瘦体重、等张卧推和腿举以及等动慢速、快速和力量耐力指标有显著变化。慢跑阶段在跑步机运动时间和VO2max方面引起了显著更大的变化。在慢跑阶段，总皮褶厚度和腰围进一步减小。慢跑期间腿部力量得以维持，但上身力量显著下降。在最后8周生理水平保持稳定，CST组和慢跑组之间没有差异。
